Q: Top seed Murray, 30, is trying to reach the last eight in Paris for the sixth time in the past seven years.
Khachanov, 21, is ranked 53rd and plays his first Grand Slam last-16 match after beating American John Isner.
"Mentally I feel pretty good just now," Briton Murray said after beating Juan Martin del Potro in round three.
Having struggled with fitness and form during much of the year, the Scot played superbly to see off the Argentine in straight sets on Saturday.
"After each round, I'm not thinking about winning," he said.
"I didn't come here with the mindset that I'm definitely going to go a long way.
"I was going to try and just get through the first round and hopefully feel better each day. That's been the case so far."
Khachanov poses a new challenge for the Wimbledon champion, and it will be the Russian's first match against any of the very top names in the sport.
He said: "That is what we are looking for, to play on the big arenas like here, centre court, and to play against world number one. I'm really looking forward for it."

Khachanov was born in Moscow but has trained in Barcelona for the past three years, during which time he has risen from outside the world's top 400 to become a fixture around the top 50.
The 6ft 6in right-hander has plenty of power, as he showed in seeing off big-serving Isner in the third round.
That followed his best win to date over 13th seed Tomas Berdych.
"I practised with him before he got on to the tour when he was like 350, and he was really good," said Murray.
"Big, strong guy. Generates a lot of power. He's also got a big serve."
Khachanov has hit 29 aces to Murray's 16 in the tournament, and has spent an hour less on court at just under the eight-hour mark.
Murray will head into the match with a very different mindset, however, following his impressive performance against Del Potro.
"I believe in myself, so even when things aren't going well, I believe I can turn it around," said Murray.
"The five-set format has definitely helped that, so I have maybe not been as anxious going into some of the matches, because I know there is some time to turn it around."

A: World number one Andy Murray will face up-and-coming Russian Karen Khachanov in the fourth round of the French Open at about 11:30 BST on Monday.

Q: Martyn Waghorn gave Ipswich the lead against the run of play when he swept the ball past keeper Daniel Bentley.
Bartosz Bialkowski made two good saves before Nico Yennaris hit the bar and Florian Jozefzoon missed a free header as Brentford went close to equalising.
But Joe Garner doubled Town's lead with a powerful header from a corner to help Mick McCarthy's side clinch the win.
Ipswich had failed to win any of their past five Championship matches against Brentford, but goals from summer signings Waghorn and Garner saw them extend their 100% start to the season.
Waghorn has hit the ground running since joining from Rangers earlier this month and scored his fourth goal of the campaign, following good work from David McGoldrick.
Brentford had their chances, with Kamohelo Mokotjo and Ollie Watkins going close, but Garner's header, which was confirmed by goalline technology, ensured Ipswich kept pace with Cardiff City at the top of the Championship.
Former Rangers strike duo Waghorn and Garner have now scored a combined seven goals in just seven Championship appearances between them.
Ipswich manager Mick McCarthy:
"It was a thoroughly professional performance against a very good side. Everyone put in a shift and I could praise everybody for their performance.
"Bart (Bialkowski) made the saves when needed and it was just a whole team performance.
"Last season we didn't look like scoring at all and we do this year. It's lovely for the lads, for me and the supporters to see goals go in. They are a threat and it's great to see."
Brentford boss Dean Smith:
"That's certainly the word I'd use at the moment, frustration. We made one mistake in the first half and they score. We should have been out of sight in the first half, we were excellent.
"We created a number of chances and didn't take them. I believe if we score when we're on top then we win the game comfortably.
"We have to keep believing in what we're doing. I'm optimistic, but I'm cautious that we're losing games which we shouldn't lose."

Q: The 23-year-old suffered a significant tear in his quad and is likely to miss the autumn internationals having become the latest player to get hurt during England's training camp in Brighton.
Wasps' Sam Jones broke his leg while Bath's Anthony broke his jaw.
"He was loaded pretty heavily on Monday, far heavier than we would have loaded him with his training," he said.
Nowell had missed the start of the season after having surgery on a thumb injury, and had only made one replacement appearance.
But Baxter was particularly critical of the England medical team for failing to realise the extent of his star player's injury.
"We were told there was no significant injury and England didn't feel it was a big issue, just an overload issue, but when we get him back here and we scan him we find a significant tear of his quad," the former lock added.
"It's not a one or two centimetre tear, we're talking a nine or 10 centimetre tear.
"For that not to get picked up is a bit annoying and now we've realised that he's going to be out for a significant period of time."
Premiership rugby have criticised the timing and intensity of the training camp, which also led to Ollie Devoto and Henry Slade missing training time when they returned to Sandy Park.
Baxter says Premiership clubs must get together with England to ensure this situation does not happen again.
"Injuries will happen, but the amount of injuries that came out of this two-day camp are so significant that if questions weren't asked, it wouldn't just be remiss of us as Premiership coaches, it would be very remiss of England not to ask how all those injuries happened.
"I don't really care if England think they have an unlimited supply of players, that's fine, but there isn't an unlimited supply of players.
"You don't have to have many training camps where you pick up five or six significant injuries before you get through your whole playing group."

Exeter head coach Rob Baxter has criticised the England set-up for overloading winger Jack Nowell.
